City Council Speaker Christine Quinn endorsed Bill de Blasio for mayor on Tuesday, saying her former rival will be a “terrific mayor,” according to a CBS New York report.

“We’re here today after a campaign and it was a hard-fought campaign by all and campaigns are, you know, at their essence, about drawing contrasts between yourself and your opponent. But I’ve got to tell you, I trust Bill de Blasio, I believe he will be a terrific mayor for the city of New York,” Quinn said when asked about a previous campaign statement that said New Yorkers cannot trust de Blasio.

Quinn, who also ran an unsuccessful mayoral bid for the Democrat Party’s nomination appeared with de Blasio on the steps of City Hall .

De Blasio said,“We understand people are going to have differences. And by the way, I respect Christine Quinn for being a fierce competitor. When she’s out on the playing field, she plays hard and I say amen.”

De Blasio’s campaign released a statement earlier regarding the endorsement.

“I am proud to stand with Bill de Blasio – the next mayor of New York City,” Quinn said in the statement. “It is time for Democrats throughout our city to put aside their differences and fight together for the progressive values we all share.”

De Blasio said in the statement “it is an honor” to receieve Quinn’s support.

“I look forward to working with her to move our great city forward,” de Blasio said.

Quinn came in third in the Democratic primary last week, and her endorsement follows that of Bill Thompson, who conceded to de Blasio on Monday alongside New York Gov. Andrew Cuomo, avoiding a runoff.

De Blasio faces Republican Joe Lhota, a former aide to Rudy Giuliani, in the November general election.
